[CentOS 5.5] MySQL stop gives access denied error

[Saurabh Pillai]

I am in /etc/init.d directory.

[root@XXX init.d]# sudo mysql stop
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
[root@XXX init.d]# sudo /etc/init.d/mysql stop
Shutting down MySQL........                                [  OK  ]

Why first command gives error(even though I am in proper directory) while second command works OK?

Hi Saurabh Pillai,

Firstly, I'm not mysql expert, however, below are my guesses:

1) My first guess was, you are using mysql command without password (and you provided password in config file), and that is the reason for 'using password: NO' thing.
2) However, your second command is interesting. It works with full path, but doesn't work with simple command. As of this, my (another) guess is - path defined for mysql in PATH variable is different from actual path (or more than 1 versions of mysql are there etc.).

I hope this helps.

Oh this is a good one!

The reason is quite simple.

The first command is invoking the mysql client application program. The root user has not been given mysql access rights to the database named "stop" when accessing from localhost.

The second command works, because it's a shell script that controls the actual mysql server daemon. Except I thought its name was supposed to be "mysqld"

I missed it...

They are totally 2 different commands, the one in init.d is a script (you can proly check by using cat mysql inside init.d folder) and the mysql(anywhere) on the first one is also different(proly the one in /usr/bin you can check by using which command 'which mysql') . I think the one you need is the 2nd one. the first one is the client app.
